Suspend MS Edge Browser Support

[brianjbayer]

What

This changeset suspends official project support for the Microsoft Edge browser. It is unfortunate that some companies are more interested in selling a product instead of making a product worth selling.

Things may change in the future, so I am commenting out the support instead of fully removing it. It may also be of use as a potential reference.

In addition, this changeset addresses a bug where double brackets ([[ ... ]]) were used instead of single brackets ([ ... ]) in the dockercomposerun script which is shell and not bash.

Why

Support for MS Edge is being suspended due to...

1. Its user-experience disruptive Personalize your web experience popup which would require browser-specific customization
2. This Selenium issue which seems to be triggered in the CI Run
3. Unable to run the selenium-standalone-edge browser image on Apple Silicon

I added MS Edge support as a nice to have but as seems to be common with Microsoft, we can not have nice things.

Change Impact Analysis and Testing

• CI Checks vet no regressions
• Inspection of CI Checks output verifies CI is not using MS Edge and fix of single brackets
• Successful execution and inspection of output of native (Apple Silicon) run of dockercomposerun ensures fix of single brackets results in no regressions
• Manual inspection of rendered README on this branch verifies documentation update
